This 1/2″ long SecureFit Extender attaches to a SecureFit CCD spacer to add 1/2″ of spacing to an optical path. The extenders are stackable so if you need an extra 1.5″, then you need three SecureFit extenders.
The back plate on all of the CDK models has four mounting positions for a finder mounting plate.
The finder mounting plate attaches to the back plate of the telescope and the quick-release finder bracket attaches to the mounting plate.
If the telescope is used on a German Equatorial mount it may be convenient to purchase two finder scopes, one for the east and one for the west side of the telescope.
The finder scope is a Baader 10×60 Varios with mounting rings and L- bracket.
